Flonase and flu

Two weeks ago I started Flonase.After the first day I became achy all over. Thought I had the flu. On the third day of using it I wasn't able to sleep. I was restless, nervous. I believe it may have interacted with my Zyrtec that I take for chronic hives. I took both meds at bedtime which was probably a mistake. After the third day of using it I got a sore throat. Not scratchy or raw but really sore. It hurts when I swallow. I have had the sore throat for nearly 2 weeks now. I also got a yeast infection about a week after I used the product. I used a 3 day treatment for that and hope it is gone, even though I still have a little irritation from the yeast infection. Needless to say, I won't use Flonase again, apparently my body can not tolerate it.
